Overview

Package stacks provides operation for working with Heat stacks. A stack is a group of resources (servers, load balancers, databases, and so forth) combined to fulfill a useful purpose. Based on a template, Heat orchestration engine creates an instantiated set of resources (a stack) to run the application framework or component specified (in the template). A stack is a running instance of a template. The result of creating a stack is a deployment of the application framework or component.

Prepare required import packages

import ( 

"fmt"
"github.com/gophercloud/gophercloud"
"github.com/gophercloud/gophercloud/openstack"
"github.com/gophercloud/gophercloud/openstack/orchestration/v1/stacks"

)

Example of Preparing Orchestration client: 

client, err := openstack.NewOrchestrationV1(provider,  gophercloud.EndpointOpts{Region: "RegionOne"})

Example of List Stack: 

all_stack_pages, err := stacks.List(client, nil).AllPages()
if err != nil {
    panic(err)
}

all_stacks, err := stacks.ExtractStacks(all_stack_pages)
if err != nil {
    panic(err)
}

for _, stack := range all_stacks {
    fmt.Printf("%+v\n", stack)
}

Example to Create an Stack 

// Create Template
t := make(map[string]interface{})
f, err := ioutil.ReadFile("template.yaml")
if err != nil {
    panic(err)
}
err = yaml.Unmarshal(f, t)
if err != nil {
    panic(err)
}

template := &stacks.Template{}
template.TE = stacks.TE{
    Bin: f,
}
// Create Environment if needed
t_env := make(map[string]interface{})
f_env, err := ioutil.ReadFile("env.yaml")
if err != nil {
    panic(err)
}
err = yaml.Unmarshal(f_env, t_env)
if err != nil {
    panic(err)
}

env := &stacks.Environment{}
env.TE = stacks.TE{
    Bin: f_env,
}

// Remember, the priority of parameters you given through
// Parameters is higher than the parameters you provided in EnvironmentOpts.
params := make(map[string]string)
params["number_of_nodes"] = 1
tags := []string{"example-stack"}
createOpts := &stacks.CreateOpts{
    // The name of the stack. It must start with an alphabetic character.
    Name:       "testing_group",
    // A structure that contains either the template file or url. Call the
    // associated methods to extract the information relevant to send in a create request.
    TemplateOpts: template,
    // A structure that contains details for the environment of the stack.
    EnvironmentOpts: env,
    // User-defined parameters to pass to the template.
    Parameters: params,
    // A list of tags to assosciate with the Stack
    Tags: tags,
}

r := stacks.Create(client, createOpts)
//dcreated_stack := stacks.CreatedStack()
if r.Err != nil {
    panic(r.Err)
}
created_stack, err := r.Extract()
if err != nil {
    panic(err)
}
fmt.Printf("Created Stack: %v", created_stack.ID)

Example for Get Stack 

get_result := stacks.Get(client, stackName, created_stack.ID)
if get_result.Err != nil {
    panic(get_result.Err)
}
stack, err := get_result.Extract()
if err != nil {
    panic(err)
}
fmt.Println("Get Stack: Name: ", stack.Name, ", ID: ", stack.ID, ", Status: ", stack.Status)

Example for Find Stack 

find_result  := stacks.Find(client, stackIdentity)
if find_result.Err != nil {
	panic(find_result.Err)
}
stack, err := find_result.Extract()
if err != nil {
	panic(err)
}
fmt.Println("Find Stack: Name: ", stack.Name, ", ID: ", stack.ID, ", Status: ", stack.Status)

Example for Delete Stack 

del_r := stacks.Delete(client, stackName, created_stack.ID)
if del_r.Err != nil {
    panic(del_r.Err)
}
fmt.Println("Deleted Stack: ", stackName)

Summary of Behavior Between Stack Update and UpdatePatch Methods :

Function | Test Case | Result

Update() | Template AND Parameters WITH Conflict | Parameter takes priority, parameters are set in raw_template.environment overlay Update() | Template ONLY | Template updates, raw_template.environment overlay is removed Update() | Parameters ONLY | No update, template is required

UpdatePatch() | Template AND Parameters WITH Conflict | Parameter takes priority, parameters are set in raw_template.environment overlay UpdatePatch() | Template ONLY | Template updates, but raw_template.environment overlay is not removed, existing parameter values will remain UpdatePatch() | Parameters ONLY | Parameters (raw_template.environment) is updated, excluded values are unchanged

The PUT Update() function will remove parameters from the raw_template.environment overlay if they are excluded from the operation, whereas PATCH Update() will never be destructive to the raw_template.environment overlay. It is not possible to expose the raw_template values with a patch update once they have been added to the environment overlay with the PATCH verb, but newly added values that do not have a corresponding key in the overlay will display the raw_template value.

Example to Update a Stack Using the Update (PUT) Method 

t := make(map[string]interface{})
f, err := ioutil.ReadFile("template.yaml")
if err != nil {
	panic(err)
}
err = yaml.Unmarshal(f, t)
if err != nil {
	panic(err)
}

template := stacks.Template{}
template.TE = stacks.TE{
	Bin: f,
}

var params = make(map[string]interface{})
params["number_of_nodes"] = 2

stackName := "my_stack"
stackId := "d68cc349-ccc5-4b44-a17d-07f068c01e5a"

stackOpts := &stacks.UpdateOpts{
	Parameters: params,
	TemplateOpts: &template,
}

res := stacks.Update(orchestrationClient, stackName, stackId, stackOpts)
if res.Err != nil {
	panic(res.Err)
}

Example to Update a Stack Using the UpdatePatch (PATCH) Method 

var params = make(map[string]interface{})
params["number_of_nodes"] = 2

stackName := "my_stack"
stackId := "d68cc349-ccc5-4b44-a17d-07f068c01e5a"

stackOpts := &stacks.UpdateOpts{
	Parameters: params,
}

res := stacks.UpdatePatch(orchestrationClient, stackName, stackId, stackOpts)
if res.Err != nil {
	panic(res.Err)
}
